This makes the installation much faster (on machine which have enough
memory).

You can write a hook and redefine mkramdisk as a noop subroutine.  A
future version of FAI will have a variable, which holds a list of all
directories that will be put into a ramdisk. If this list is empty, no
ramdisk will be created. But it's not yet implemented.
